LOOM SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 372,239, dated October25,1887.

Application filed April 27, 1831. Serial No. 236,360. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES GUSTAV ROOT, of San Quentin, Marin county,State of California, have inventedan Improvement in Loom- 5 Shuttles;and I hereby declare the following to befia full, clear, adamantdescription o fthe same.

My invention relates to shuttles such as are employed to carry thebobbins in weaving fabric; and it consists in the combinatiomwith ashuttle-body, of the improved tip and fastening-bolt hereinafterdescribed.

Referring to the accompanying drawings for a more complete explanationof my invention, Figure 1 is a side view of one end of the shuttle,showing the tip in place. Fig. 2 is a plan view thereof; and Fig. 3 is asectional viewof the cap removed, showing the bolt bywhich it issecured.

In the manufacture of loom-shuttles it is customary to protect theend ofthe shuttlebody by means of a flat plate which is variously secured tothe shuttle-body and has a spur or point projecting from one sidethere-- of, Which serves to insure the passage of the shuttle properlybetween the threads of the warp, while a portion of the fiat plateserves to receive the impulse of the picker which throws the shuttlefrom end to end of its travel. These plates are sometimes secured to theend of the shuttle'by means of two pins which project from the plate andare driven into the end of the shuttle, or they may be secured by meansof screws, one of which has its head countersunk to fit flush with thesurface of the plate, while the other is provided with a pointedextension, as before described. I11 either case the rapid movement ofthe shuttle and the violent blows to which it is subjected cause thewood to become split in a short time, or the plates to be loosened, and,furthermore, the shuttle-bodies are very often split and broken in theact of putting the plates on. In my invention, A is a metallic cap, madeof 5 sufficient length to have a chamber, B, formed within itsIarger endofthe same shape as the end of the shuttle to which it is to be fitted.

O is the pointed tip which insures the proper passage of the shuttlebetween the threads, as before described. A countersunk hole, D, is madethrough the centmlportion ofrtliew llcr-r tallic tip, and a bolt, E,passes through this hole and a corresponding one in the end of theshuttle, so that it enters the central open space within the body of theshuttle. A nut, F, is

screwed upon the threaded end of this bolt,

her adapted to receive the end of the shuttlebody, a bolt passingthrough said chamber and the end ofthe shuttle-body,havingaheadcountersunk in the outer end or wall of the tip,and a securingnut on theinner end of said bolt, substantially as herein described. 2. Thecombinatiomwith a shuttle-body, of a metallic cap having a pointed tip,0, and a chamber by which said cap is fitted to the end of the shuttle-body, and a bolt passing through said cap and the end of theshuttle-body, hav- 8o ing at one end a head countersunk in said cap andat the opposite end a securing-nut, substantially as described.

ln witness whereof I have hereunto set my hand.

CHARLES GUSTAV ROOT.
